            Bug ID: 233253
           Summary: [GLIB] jsc_value_object_define_property_accessor()
                    throws an exception when called on a value without a
                    wrapper instance
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore

We assumed that getter and setter were always methods, so we always try to set the initial parameter as the instance. When called with a value ot having an instance we get an exception because the expected instance is nullptr.
